Genomic detection (+ , present; - , not present) of C. parvum in feces of calves orally challenged with C. parvum oocysts (0-day post-challenge, dpc), which were fed milk replacer (C. parvum/MR) or colostrum (C. parvum/C).

*Calves that received same volumes of PBS rather than C. parvum oocysts at 0 dpc and were fed milk (Sham/MR; n = 5) or colostrum (Sham/C; n = 6) were negative to C. parvum during the study.
